Abstract
A method of displaying an image includes alternating an active state of each of a plurality of light sources. The light sources each generate a light beam when active. The alternating includes deactivating an active light source before an output of a light beam from the active light sources falls below a first predetermined threshold. The alternating further includes activating a deactivated light source only after an output of the inactive light source reaches a second predetermined threshold. The method further includes receiving each of the light beams at a spatial light modulator.
Claims19
A method of displaying an image, comprising:
- alternating an active state of each of a plurality of light sources, the light sources each generating a light beam when active, the alternating comprising:
- deactivating an active light source before an output of a light beam from the active light source falls below a first predetermined threshold;
- and
- activating an inactive light source only after an output of the inactive light source reaches a second predetermined threshold;
- and
- receiving each of the light beams at a modulator, the modulator comprising an array of micro-mirror devices.
A method of displaying an image, comprising:
- successively activating and deactivating respective ones of a plurality of light sources for illumination of a spatial light modulator during an image display time, each light source generating a respective different color light beam when activated, and the light beam of each light source having an output brightness that decreases with rising temperature as the light source heats up when activated, including:
- deactivating each activated light source before the decreasing output brightness of the associated light beam due to heating falls below a first predetermined brightness threshold;
- and
- reactivating each deactivated light source only when the light source has sufficiently cooled to enable the output brightness of the associated light beam to reach a second predetermined brightness threshold when that light source is reactivated.
